SICLOCK ® TC100 Operating Instructions
9.1 Connecting external synchronization
The external synchronizations can be connected to SICLOCK TC100 via
Ethernet as an NTP server and/or as a radio clock via point-to-point connections.
The prerequisite for operation is at least one external synchronization. Additional
external synchronizations can serve as substitute synchronizations in the event
of a fault, see Redundancy (Chapter 2.6).
GPS and DCF77 radio clocks, cable distribution installations, atomic clocks and
other signal sources can serve as external synchronizations.

Synchronization (Chapter 9.3.2).
9.1.1 Radio clocks via terminals
A radio clock can be connected, see also Terminal assignment (Chapter 15.1).
Monitoring
The input signal of the radio clock can be monitored with the parameter
/Inputs/Input 1/Monitoring (0.20.01), and an alarm or warning output after expiry
of the monitoring time.
Status display
See Connecting external synchronization (Chapter 6.3).
Serial formats
The parameter /Inputs/Input 1/Framing (0.20.03) shows the automatically detec-
ted framing for serial formats.
There are entries for baud rate, data bits, parity and stop bits.
